Add Columns to new Company Tab

I have added a tab in the "Company Detail" window. Below the Company information by default you have several tabs. ie... Contacs, Notes, History, Activities, Opportunities, Documents, Addresses and Company Info.

I have added a Tab next to "Notes" that I call "Eng Notes". What I am trying to do is to duplicate the Columns in the "Notes" tab

for the new "Eng Notes" tab. Is this possible. I can't seem to figure out how to add a Column?

Re: Add Columns to new Company Tab

Notes is an Act generated relational tab, it's not possible to "copy" it using the layout editor. The only way to add another tab that displays either notes, or histories in some custom way would be using a custom add-on.
